To all wh-om 'it may concern:

lie it known that l, (lis'rar A. llnnMA'NN Klemmen, of Rochester, in thecounty of Monroe and State of New York, have inrented certain new anduseful lmprovements in bltereoscopic rippliances; and I do herebydeclare the following to be a full, clear, and exact description of thesame,ref erence being had to the accompanying drawings. forming a partof this specification, and to the reference-numerals marked thereon.

This invention relates to stereoscopic appliances, such as stereosco-pesand stereoscopie cameras. ,i

A stereoscopic camera, as is well known, produces the two images in aposition which is the reverse of that in which they are viewed throughthe ordinary stereoscopc and as a consequence it is necessary to cut thefinished picture to transpose the images.

The object of this invention is to obviate this transposing of theimages by providing a means for deflecting the rays between the lensesof a stereoscopic camera or a stereoscope and the image without.foreshortening the image, so that, by the camera, the two images areproduced in positions suitable for an ordinary stereoscope, or, by thestereoscope when they are produced in reverse po` sitions, they may beviewed without the. usual transposition by cutting. Further, theinvention when applied to stereoscopic ca1neras may be constructed tovposition the images in any relation to each other and when applied tostereoscopes may be constructed to suit any relative position of thelmages.

To these and other ends the invention consists in certainimprovementsand combinations of parts all as will be hereinafter morefully described, the novel features being pointed out in the claims atthe end of the specification.

In the drawings: Fi ure 1 is a top View of a stereoscope emb ying myinvention; Fig. 2 is a section on line a-a of Fig. l; Fi 3 is adiagrammatic view of the same em odiment Fig. 4 is a diagrammatic viewof another embodiment Fig. 5 is a top View of the embodiment shown inFig. 4, and, Fig.

6 is a section on line b--b Fig. 5.

The invention is herein shown and de` scribed as embodied in astereoscope which in this instance preferably comprises a suitablesupport, or base l having thereon a front board or other suitable member2 formed with view openings in which are preferably arranged suitablecollectivel lenses 3. A1'- ranged preferably on the base l is asuitable. y

image holder ladapted to hold two images in the same plane. The opticalrelation be tween the images and the lenses or vie\\ openings ismaintained, without causing a foreshortening of the image, by a series'of detiectors suitably arranged to accomplish this result.

1n the embodiment shown in Figs. l to 3 the images land 6 are arrangedin a'vertical plane and in horizontal alinement and a peneil of rayspasses from each view opening or lens 3 to a reflector 7 arranged at anangle of 45 to the pencil, thence at right angles to a reflector 8 alsoarranged at 45, and finally to the image 5 or 6, that portion of eachpencil between the reflectors 7 and 8 crossing the other and causing atransposition of the images, only one pencil being shown in Fics. 1 and2 so that the illustration will be c ear. i

In the embodiment shown in Figs. 4, 5 and 6, the images 5a and 6a arearranged in the same vertical plane and are out of horizontal alinementand the encil, in one instance, passes to a reflector a arranged at anangle of 45 thereto, thence upwardly to aretiector 8a also arranged atan angle of 45 and finally horizontally to the image 5a; and, in theother instance, passes to a refiector 7b ar. ranged at an angle of 45thence down'- wardly to a reflector 8b also arranged at an angle of 45and finally horizontally to the image 6a. The images in this instancemay be arranged on rolls 9 and 10 and fed in any suitable manner as forinstance by handlell to give a panoramic eect. The image holder in bothinstances may be adjusted 1n the direction of the optical axis of thedevice as by a block 12 working in a slot 13 in thebase" to accommodatethe eyes of different persons. Of course with different sizes of imagesthe relation of the parts will have to be changed and for this reason Iprovide means permitting the shifting of the axis of the pencil on theimage which in thisv instance comprises a screw 14 working in a slot 15so that the reflectors 7 a and 7 b are adjustable in the direction ofthe axes ofthe pencils (see Figs. 5 and 6). v

It is to be understood that lthe term lenses herein employed is used forthe purpose of including the lenses of a stereoscopic camera or thelenses of a stereoscope and that theterm image holder is employed asgeneric to a negative holder of a stereoscopic camera or a pictureholder of a stereoscope.

I claim as my invention.

1. `In a stereoscopic'applianc'e, theV combination with a holder adaptedfori'. images in one plane and a member having a pair of View openings,4of two reflectors lfor each` pencil of rays, arranged with theirreflecting surfaces arallel with'each other and at angles to th relationbetween the View openings and the image holder.

2. In a stereoscopic appliance, the combi! nation'with a holder ada tedfor images in one plane and a pair of. enses', of two re liectors foreach pencil of rays', 'arranged lwith their reflecting surfaces parallelwith each other and at 'angles to the pencil of rays and maintainingoptical relation between the lenses and the image holder.

3. In a stereoscopic appliance, the combie pencil and maintainingoptical nation with an image holder for a pair of pencil arranged atsuch angles to each other andv to the View 'openings and the imageholder that the images are transposed without bei-ng reversed.

4. In a stereoscopic ap liance, the combination with an lmage ho der anda member havmg a pair of view openings, of means `for maintainingoptical relation between said View openings andthe image holderconsisting of a pair of deflectors for each View opening having theirdeflecting surfaces arranged substantially parallel to each other, theaxis of the rays between one pair of deliectors, being arranged to crossthe vaxis ofthe raysbetween the other pairof deflectors.
